INTRODUCTION For millennia mankind has inhabited the third planet from the sun; the planet that supports life and is know to us as Earth. Although there has been life on Earth for quite sometime‚ it is only in the past few centuries that man has come to learn about what makes up the interior of this planet. The English scientist‚ Isaac Newton‚ can be seen as a pioneer in regards to learning about the Earth ’s interior‚ as he calculated from his studies of planets and the force of gravity‚ that

When most people think of a national park they think of Yellowstone or Yosemite or the Grand Canyon but what they should think of is the Isle Royale National Park. The reason is because the Isle Royale is what a national park should be which is wild‚ rugged‚ and buffered from the outside world. The Isle Royale lies in northwest Lake Superior and although its only just 18 miles of water that separate the island from its nearest mainland shore of the Minnesota-Ontario border‚ it is considered part

CheckPoint: Igneous Rock SCI245 July 20‚ 2011 CheckPoint: Igneous Rocks The answer to how igneous rocks are formed is given in their name; Igneous is Latin for “fire”. This basically means igneous rocks are cooled fire rocks from magma or lava‚ depending on where they cooled and formed. There are two categories of igneous rocks that also depend on where each was formed. Intrusive igneous rocks are igneous rocks that form when magma cools slowly and becomes solid underground. Extrusive igneous

a need for them to be stored in better ways. This process led to the formation of a skilled artisan culture to do so‚ which produce a form of social mobility and a way out of destitute and serfdom for the peasantry class. The artisanship in Mesoamerica did create a huge impact on the trade of goods within the Aztec empire‚ and as a result of the burgeoning class of skilled workers‚ along with the superior craftsmanship of their labor‚ goods along with crops could be preserved and moved at longer

the pressure and tension build up‚ rocks in the plates break and results in earthquakes. Spreading Mid ocean ridges are places where the Earth’s tectonic plates spread apart from each other as hot magma emerges from the mantle and oozes forth as lava to fill the gap constantly created by the plate separation. This is called diverging. As it cools it forms new ocean floor crust. This process is known as sea floor spreading. Colliding When two continental plates move towards each other‚ they

“Discuss the Extent to which volcanic and seismic activity are evidence for plate tectonic theory” (40) Plate tectonics is the theory that explains the structure and motion of the Earth’s lithosphere. The theory states that the Earth’s crust is split into large sections called tectonic plates‚ and these move relative to one another creating boundaries at which plates converge‚ diverge and move past each other. Alfred Wegener pioneered the theory of continental drift in the early 1900s which he supported
